N-bromobutanimide → 4-(7-Bromo-2-(4-cyanophenylamino)-5-methyl-5H-pyrrolo[3,2-d]pyrimidin-4-yloxy)-3,5-dimethylbenzonitrile

Participants

Reaction Steps

To a solution of 4-(2-(4-cyanophenylamino)-5-methyl-5H-pyrrolo[3,2-d]pyrimidin-4-yloxy)-3,5-dimethylbenzonitrile (58 mg, 0.15 mmol) in CH2Cl2 (8 mL) was added NBS (29 mg, 0.16 mmol) and the resultant mixture was refluxed for 16 h. After completion of the reaction, the solvent was concentrated and purified by preparative TLC, eluting with hexanes:ethyl acetate (2:1), to give the product as a yellow solid (40 mg, 57%).
